Detailed Description

template<typename GeometryIterator, typename PartIterator, typename RingIterator, typename VecIterator>
class cuspatial::multipolygon_range< GeometryIterator, PartIterator, RingIterator, VecIterator >

Non-owning range-based interface to multipolygon data.

Provides a range-based interface to contiguous storage of multipolygon data, to make it easier to access and iterate over multipolygons, polygons, rings and points.

Conforms to GeoArrow's specification of multipolygon: https://github.com/geopandas/geo-arrow-spec/blob/main/format.md

Template Parameters

GeometryIterator	iterator type for the geometry offset array. Must meet the requirements of LegacyRandomAccessIterator.
PartIterator	iterator type for the part offset array. Must meet the requirements of LegacyRandomAccessIterator.
RingIterator	iterator type for the ring offset array. Must meet the requirements of LegacyRandomAccessIterator.
VecIterator	iterator type for the point array. Must meet the requirements of LegacyRandomAccessIterator.

Note

Though this object is host/device compatible, The underlying iterator must be device accessible if used in device kernel.
